Colin Baker, in his article in the Bucks Free Press (Nov. 21) makes the analogy between the believers in a flat earth some 800 years ago with scientifically educated readers like myself who are climate change sceptics.

We are not climate change deniers. A denier is someone who, when presented with proven evidence denies it ever existed. A sceptic is someone who challenges the validity of the evidence.

Proven scientific evidence collected from temperature records and cores drilled deep into the ocean bed and the polar ice caps tells us that the global climate has always changed irrespective of any human input.

The fact that glaciers are retreating and the north polar ice has been reducing since 1979 is no proof that it is being caused by the burning of fossil fuels. It is more likely to be part of the constant heating and cooling of the planet that has been a continuous process since the end of the last ice age 8,000 years ago. This is a natural process which will continue until the planet enters the next Ice Age in about 2,500 years time.

The predictions of the IPCC are based solely on computer modelling which has, from past evidence, shown to be dangerously misleading. The UK Metrological Office, a primary source of computer generated climate data used by the IPCC, forecast in 2004 that the mean global temperature would increase by 0.8C by 2014. We are now at the end of 2014, there has been no increase in global temperature since 1998 and in recent years there has been a reducing trend in the mean global temperature.

It was Joseph Goebbels the German Minister of Propaganda who stated “if you lie to the people long enough and hard enough they will eventually believe you”. That statement is as true today as it was 80 years ago when you analyse many of the predictions from the IPCC. It would appear from Colin Baker’s Look Who’s Talking column that he is a victim of this philosophy. - Anthony Weeden, nr Marlow
